Valve Stem Oil Seals - Different Types

[axnutty 10]

My engine is under going a full rebuild and as part of such I am replacing the valve stem oil seals. I bought a set on ebay and didnt pay them too much attention but having just got round to fitting them they are a different construction to the ones im taking off.

 

The old ones are green rubber type, with a metal clip round the base and a small spring clip round the top.

 

The new ones are made by a company called FAI and are just white hard plastic with a simple metal clip at the bottom.

 

This prompted me to do some google action and I found this click which details the many different types of material used. Blatantly the new seals are of a different construction to the old ones (which I presume is OEM) Has anyone got any experience of FAI as a company. Or of the FAI type seal?

 

Its one of those jobs I would hate to have to redo next week if they turn out to be crap

I've never come across any without a coil spring on...they're pretty important to the seal. As such, I'd return, get a refund and stick to a better brand. Something like Febi should be fine but I went with Victor Reinz as I've read the quality is top notch.

Yeah ive since spoken to a mate you runs a garage and he advised the same saying he has used FAI autoparts for customers cars before and had problems with logetivity of suspension components. Bugger... thats put the rebuild back. Bloody annoying when you work all the time and then you get a few days off and cant do anything because of stupid situations like this.
